Bug ID: 22352
   Summary: GAS doesn't complain about same register used for
destination and index in AVX512 gather insn when
destination is XMM
   Product: binutils
   Version: 2.30 (HEAD)
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: gas
  Assignee: unassigned at sourceware dot org
  Reporter: craig.topper at gmail dot com
  Target Milestone: ---

I think some cases were missed from the fix for bug 16489. This instruction
doesn't emit a warning

 vpgatherqd (%r14, %ymm11,8), %xmm11 {%k1}

while this instruction does emit a warning

 vpgatherqd (%r14, %zmm11,8), %ymm11 {%k1}
